【正文】 the basic functions of a personal firewall, this system is easy to operate and has friendly interfaces. Key words Personal Firewall。 用戶界面用 MFC 實(shí)現(xiàn)。 本文根據(jù)個(gè)人防火墻的實(shí)際需求，首先分析了目前市場(chǎng)上各類防火墻所采用的不同核心過(guò)濾技術(shù)，結(jié)合其優(yōu)缺點(diǎn)和實(shí)現(xiàn)的難易程度，確定了本課題實(shí)現(xiàn)所采用的技術(shù)并 做出相應(yīng)的闡述。 I 摘要 隨著互聯(lián)網(wǎng) 的普及，安全問(wèn)題越來(lái)越受到大家的重視。 因此，開(kāi)發(fā)有效的個(gè)人防火墻具重要 意義。核心過(guò)濾驅(qū)動(dòng)的開(kāi)發(fā)采用 Visual Studio 2020 和 Windows 下的驅(qū)動(dòng)開(kāi)發(fā)工具 WDK 進(jìn)行編碼和編譯 ， 用戶層采用 C 語(yǔ)言進(jìn)行編寫(xiě)。 關(guān)鍵詞 個(gè)人防火墻 ； 數(shù)據(jù)包過(guò)濾 ； FilterHook Driver； 網(wǎng)絡(luò)安全 II Abstract With the popularity of the Inter, security issues are attention by more and more people. A secure work environment can protect personal puter from Trojans and viruses, and provide necessary protection to people39。 Network security 目錄 摘要 ............................................................................................................................................
